Fibrinogen is a glycoprotein found in the blood that is converted into fibrin during blood coagulation. Fibrinogen is cleaved by another protein, thrombin, exposing knobs A and B to form fibrin. [1] It is this fibrin that forms clots to prevent excessive bleeding from wounds sustained. Clotting factors, like factor XIII, are often linked to fibrin. [2] Fibrinogen is composed of 2 copies each of 3 non-identical chains alpha, beta, gamma (, , ).
